TABULATING ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 785,983, dated March28, 1905.

' A li ati fil d April 25, 1904. Serial No. 204,918.

To aZZ whmn it may concern;

Be it known that I, WALTER JEssE SPIEO, a citizen of the United States,residing at New York, in the county ofNew York, State of New York, haveinvented certain new and useful Improvements in Tabulating Attachments,of which the following is a specification, reference being had thereinto the accompanying drawings.

This invention relates to a tabulating attachment for type-writers, andparticularly to a structure embodying a series of carriagestops such,for instance, as shown in the patent to Charles Spiro, No. 5%,111, datedJuly 23, 1895-associated with a carriage-release device, whereby asimultaneous movementof both the stop and release mechanisms isobtained.

The invention has for an object to provide an improved construction andarrangement of the stop-keys relative to the release-key whereby thesekeys may be simultaneously depressed or operated to interpose a stop inthe path of the stop-rack of the carriage and to remove or release theregular feeding mechanism from the carriage.

Afurther object of the invention is to pro vide a construction andarrangement of the stop-levers and associated parts whereby they may benested or disposed within aminimum space and properly arranged forindependent operation from a keyboard.

Another object of the invention is to provide means upon the stop-keysfor permitting a movement of said keys after the stop is thrown inposition and for the purpose of effecting the release of the feedmechanism from the carriage through a separate device operablesimultaneously with the stop-keys.

Another object of the invention is to provide an improved constructionand arrangement of connecting keys and levers for the purpose ofreleasing the ordinary feed mechanism of a type-writer by jointlyremoving the dogs from the star-Wheel with which they ordinarilyoperate.

Other and further objects'and advantages of the invention will behereinafter set forth,

and the novel features thereof defined by the appended claims.

In the drawings, Figure l is a plan of a portion of a type-Writer,showing the attachment applied thereto with parts broken away and insection; Fig. 2, a side elevation with the end Wall of the casing forthe attachment removed; Fig. 3, a rear elevation of the casing for theattachment removed and parts in section; Fig. 4, a diagrammaticperspective of one of the stop connections in its associated relationwith the release connections; Fig. 5, a similar view showing thestop-rack carried by a carriage in connection with the independentoperable stops; Fig. 6, atop plan view of the escapement mechanism shownin Fig. t, and

Fig. 7 adetail perspective of one of the stopkeys.

Like letters of reference refer to-like parts in the several figures ofthe drawings.

This invention is applicable to any form or ordinary construction oftype-writer, but for the purpose of illustration is here shown inconnection with the type of machine known as a bar-lock and comprisinggenerally a frame A, having a type-bar segment A and a platen-carriage Amounted thereon, said carriage being provided with a feed-rack Acooperating with the usual escapement mechanism, as shown in Figs. 4cand 6. At one side of the platen a ribbon-carrier A* is disposed, and atthe front of the machine the usual space-bar A is connected by the keysA to oscillate the feed mechanism. The carriage is also provided at therear with a stop-rack A of usual construction and provided with stops A,pivotally mounted upon a longitudinal rod A, so as to be rotatable outof engagement with the teeth of the rack A, said stops being providedwith a recessed portion A to engage said rack and with a contacting faceA below the rack to engage with the independent stops B when the sameare thrown into the path of the stops upon the rack. These parts are ofthe usual construction, and the invention is not confined to the usethereof, as other arrangements may be provided to perform a similarfunction.

The tabulating attachment herein disclosed may be disposed in anydesired position and is here shown as contained within anangularly-formed casing attached to one side and back of a type-writer,said casing comprising an end wall G and a back wall C, while oppositethe end wall C at the back of the easing a support C is provided andadapted to receive a pivoting-rod (1 upon which each of the levers B,carrying the separate stops B, are mounted at opposite ends. Theselevers are substantially U-shaped in form, and the end portions thereofare disposed at an angle to the body and are of less length than saidbody, thus providing a pivotal mounting at each end thereof, one end, Bhaving a stop B secured thereon, while the opposite end, B is connectedwith a stop-key B by means of a ligament B, as shown in Fig. 4, whilethis key is pivotally mounted upon the cross-pin B carried by the caseof the attachment, and the outer free end of the key provided with afinger-post B pivoted thereon and at an angle thereto. As shown in Fig.7, the key B is provided at its pivotal point with a slotted aperture Band is normally held in a raised position by means of a tension-springB, extending therefrom to a fixed part. This slotted aperture permits acontinued movement of the key after the stop controlled thereby has beenthrown in position, which is necessary in order that a movement of thesimultaneously-operated escapement-key may be continued after thecompletion of the stop movement. This escapement-operating mechanism maybe constructed and arranged in any desired manner to operatesimultaneously with any one of the stops and be yet capable of movementseparately therefrom; but as showing a desirable form of thisconstruction a plate 1) is provided at the keyboard of the attachmentand formed with apertures D, through which the posts B of the stop-keysextend. This plate is pivotally mounted upon a fixed frame of theattachment, as shown at D and is connected with a release-key D by meansof a pivotal connection D", as shown in Fig. 4, the inner end of thiskey being connected by a ligament D with the angularlydisposed end ID ofthe rock-lever D which is pivotally mounted upon the rod C by means ofthe portion D and a similar portion D at the opposite end of the lever.The downward movement of this lever contacts with the U- shaped end Eofthe escapemen t-lever E, which is so shaped in order to permit a properdisposition within the back of a type-writer casing and also the pivotalmounting of the lever upon the back of the casing at E, at which pointit is also provided with a restoringspring E". The opposite end of thislever is extended at a right angle thereto, as shown at E", and thereprovided with acurved strikerface E adapted to engage an angular lip E,depending from the pivotally-mounted yoke E carried at the opposite endsof the escapelnent mechanism and there provided with fingers E one ofwhich is adapted to engage and depress the dogs F by means of a tailF'from the main pivot-d og disposed beneath the finger, while the otherlinger may be operated by a carriage-release bail. The main dog F ispivoted at its lower portion to rock away from the star-wheel E, withwhich the dogs ordinarily engage to release the escapement, and at itspivotal point is carried by the usual rocking support F, connected withthe spacebar by means of the keys A and the usual connections. Upon themain dog F the secondary dog F is pivotally mounted at F, so as to becarried away from the star in the movement of the primary dog. The staror spur wheel F is provided upon its shaft with a pinion F adapted toengage the feed-rack A of the carriage. The plate D, which controls therelease-key, may be provided with any desired marking or characters toindicate the denomination or degree of space formed by the separatestops controlled by the stopkeys disposed within the area of said plate,these parts being so arranged that the depression of the stop-keycarries with it the plate, thus primarily drawing the stop into the pathof the stop-rack on the carriage, while the slotted pivoting-aperture ofthe stop-key permits it to continue its movement downward after the stopis thrown in position, in order that the plate may fully accomplish therelease of the ordinary escapement mechanism. In the operation of theinvention it will be seen that the depression of the pivoted plate 1)carries downward the outward end of the release key D which is mountedon the pivot B and normally held in raised position by means of one ormore springs D", extending to a fixed part. The inner end of therelease-key is connected with the rocking lever D by means of theligament D extending from the key to the angular end D" of the lever.The body of this lever in its downward movement is adapted to strike theangularlydisposed end E of the lever E, pivoted upon the back of themachine-frame at E. This lever normally lies beneath the plane of thetype-keys, and the arm E thereof is extended upward therefrom betweenadjacent keys and provided with the striker-face E adapted to engage theangular lip E, depending from the release-lever E pivotally mounted uponthe frame of the escapement mechanism and having at one side of itspivot the dog-finger E adapted to engage the tail F of the primary dogF. This dog is pivoted upon the rocking plate F of the escapement, andhas pivotally mounted thereon a cooperating dog F", these dogs jointlyoperating in connection with the star or spur wheel F in the usualwell-known manner. The rocking plate F is adapted to be operated in theusual manner from the space-key of the machine to perform ITC thestep-by-step feeding function, while the engagement of the clog-fingerof the releaselever with the dogs oscillates them out of engagement withthe star-wheel, thus leaving the carriage free for movement under theusual spring tension, and this action can be accomplished by thedepression of the plate D and release-key without throwing any of thestops into position. It is, however, desirable in tabulated ordenominational work to throw a stop into engagement with the stop-rack Acarried by the carriage, and this is accomplished by the engagement ofthe finger of the operator with both the post B of the stop-key and theplate D of the release-key, thus effecting a simultaneous movement ofthese two parts to first throw a stop into the path of its rack and thenrelease the escapement mechanism. The pivotal opening in this stop-keyis, as before stated, elongated, so as to permit a continued downwardmovement of the key simultaneous with the movement of the release-keyafter the stop has been thrown in position and itsfurther travel stoppedby contact with the casing above the stoplever, while at other times thetension of the spring is suflicient to hold the lower portion of thisslot in engagement with the pivot, so that it acts upon this point as apivotal center. The series of stop-keys are independently and separatelyconnected with the several stop-levers B, which carry a stop B in adifferent relative position to the rack upon the carriage and adapted toengage the stop finger or block carried by this rack to effect astoppage of the carriage at the desired point. These stoplevers arenested one within the other, as shown in Fig. 1, so as to occupy aminimum space and to provide for a pivoting of all of the same upon acommon pivot and in the same horizontal plane, which is desirable inconnection with the structure of machine here shown.

It will be obvious that changes may be made in the details ofconstruction and configuration without departing from the spirit of theinvention, such changes being within the ordinary skill of a mechanicfamiliar with the art to which this invention relates.
